Fix --curdir on Windows

On Windows, files are canonicalized to prevent issues with legacy 8.3
filenames. However, this canonicalization includes making the path
absolute and this happened before applying --curdir to the path, making
the latter a noop.

By reversing the operations, this should allow both of them to do their
work.
